Administration of vasoconstrictor preventing maternal
hypotension after combined spinal-epidural , anesthesia(CSEA) in elective
cesarean section patients.A total of 240 full-term, single pregnancy women,
undergoing elective cesarean section in CSEA were included. Multiple linear
regression analysis was used to identify major contributing factors for
maternal hypotension from 18 independent variables. The model was set as
αentry= 0.05, αremove = 0.15, and condition index <15. The incidence of
hypotension from different combinations of vasoconstrictors for hypotension
prevention were calculated and compared, then correlated with pH and base excess
in neonatal umbilical venous blood, as well as 1 and 5 min Apgar score, using
one-way ANOVA. p<0.05 was considered to be significant difference. Continuous
dosage of phenylephrine decrease incidence of maternal hypotension after CSEA
for elected cesarean section.
